custom bass project help!

well after a couple of years of debate. I am neck deep (literally! just ordered a custom wenge on wenge fretless neck from warmoth) into a custom double book matched walnut custom bass for one of my good friends..... now I have been building fine furniture for the last 10 years but this is my first shot at a musical instrument. and to top it all off I am not a bassist. so any and all advise would be welcomed..... have been studing under a guitar builder who has helping me with basic assembly and tuning but I need help with wiring/shielding pickup selection, and a good bridge/tuner combo. all I want is for this to be a great playing and sounding bass when I give it to my friend.
cheers
btw. this is my first posting to talkbass would like to post some photos of my finished prototypes. how does one do that??
